Genus Aporcelaimus
Thorne & Swanger, 1936

Definition:  Dorylaiminae.  Characterized by the form of the guiding sheath which, at its forward end, splays out in a funnel-shaped way, the wide end joining the stoma wall as the anterior fixed ring.  This flared part is frequently plicated.  The previous interpretation of this part was that the guiding ring was absent.  The ring is almost always in the single state.
    Mostly largish species varying from 1.5 to 10 mm.  Cuticle often marked by fine interwoven straie.  Lip region offset by constriction.  Amphids stirrup-shaped; some species appearing to have a cuticularized median support.  Labial papillae in the usual apical ring of 6 and a more lateral one of 10.  Entrance to stoma dorso-ventrally elongate, more so than in Dorylaimus (sensu lato).  Spear axial, its aperture 1/2 or more of its length.  Posterior part of the oesophagus massive.  Female gonads paired, opposed, reflexed; orientation of vulva not stated for most species.  Spicules large, arcuate, dorylaimoid.  Lateral guiding pieces present.  Tails of both sexes blunt, rounded, convex-conoid to hemispherical.
